Discussion              

An Arctic air mass will loosen its grip on the region today and temperatures will modify noticeably after quite a cold start.  In fact, temperatures should climb into the 40’s this afternoon and a bit of additional warming will take place on Thursday.  After that, the trend in temperatures will be down once again with progressively colder conditions to return for Friday and Saturday as high pressure re-establishes across southeastern part of Canada. 

Later this weekend, a vigorous wave of energy in the upper atmosphere will likely help to generate surface low pressure in the southeastern states and it could have an important impact on the Mid-Atlantic region in the “later Sunday/Monday” time frame…stay tuned on this potential significant winter storm.
